AND FOUNDRY COMPANY, 0F SEATTLE,

WASHINGTON'.

Application led January To all whomy t may concern:

Be it known that I, FREDERICK IV. CHRIS- wELL, a citizen of the UnitedStates of America, and resident of the city of Seattle, in the county ofKing and State of ashington, have invented certain new and usefulImprovements in Fillers for Log Bunks, of which the following is aspecification.

My invention relates to logging bunks and consists of a construction inwhich the stakeholding and controlling elements of the bunk are made asa separate construction capable of being assembled as a whole,independentV of the bunk bot y, and inserted in or secured as a whole tothe bunk body,

- whereby the parts of a logging bunk which are most subject to breakagemay be replaced when broken without having to discard the entire bunkand all its parts.

The object` of my invention is to produce a. type of construct-ion for abunk and the essential working elements of a` bunk, such that the partswhich are most subject to breakage may be replacedor repaired at a costmuch less than wherey they are -built as `essential elements of the bunkas a whole.

rlhe particular constructions and combinations of parts upon which Idesirerto secure a patent may be seen from a study of the followingspecification and the accompanying drawing.

In these drawings I have shown abunk which embodies my invention, thesame having the constructionwhich is preferred by me for the particulartype of bunk. `vIt' is, however, evident thatfthe principles of myinvention may be applied to bunks of a different type of constructionwith as great advantage as to the type ofy construction illustrated.Figure lis alongitudinal verticalsection through the bunk and alsothrough the frame of the fillers employed.` g j Figure 2 is altransverse section' 0f the bunk body, showing the construction whichhas been illustrated .in the other figures.

with the'stake omitted and with the position of the side` members of thebunk bodyindicated by broken lines.

Practical experience with logging bunks' developed the fact that thebreakageofany essential part of the bunk, excepting as it might bethestake or the controlling bar'V therefor, made it necessary to discardthe entire bunk. It also has developed that where the bunk body isbroken this generally occurs Vat oneend and includes the parts thereofwhich are used for supporting and controlling the stakes. Such breakage,

where the bunk is made as a steel casting, involves the discarding ofthe entire-bunk.

` In my present invention the bunk body is intended to be made orpreferably should be made of wrought metal sectionswhich, whensubjectedto heavy blows such as would break a steel casting, may giveand bend but'willnot break. As this type of sections is of a` i simplecharacter, as, for instance, of the two esesntial feature, except in sofar as the same may be adapted for the reception of the filler sectionsand the parts; mounted there-on.

The fillers illustrated inthe accompanying drawings involve the use vofva frame whichl has two side members` 2O adapted whenV usedr inconnection with the" bunk body illustrated, to 'be inserted within andclosely fit between the side webs l ofl ,thev v bunk body. Thefiller'i's then secured in place by riveting or bolting.

(The two side webs 2O "are connected by transversely extending memberswhich as illustrated comprise a top web 21 and cross bars 22 and 23.Such other cross connect- `ing webs or bars as may be desired and'which' vi/,ill'fnot interfere with the action of the other parts may beemployed, e

The' ,Seite 3 eeeioyed is of Well-@Owe 75 l bulb angles and the channel10, as shown 7 in Figure 2, these may be straightened withn Q- allyprojectine bosses 8l, `which are provided With inclined supportingsurfaces 32 adapt-- ed toerig-age complementary supporting; surfacescarried by the main trame. `These are inclined so that it the Wholeaction of il the controllingl bars fl is released the tendency be 'lorthe stale tomove outwardly suticrent tolcarry the supporting trunni'ons3l Albeyondthe end of the web Qfl which forms This Web 9A-l projectsinward from each of the side Webs apart of the filler iframe.

llhey are, however7 separated a suliicient distance` to (permit. themain body ot the 'stake 3 to drop `freely between them;

The lateral position ot `thestale length- 11 ,visev ojttlie brink andotthe :filler is controlled by a bar 4L which extends to kthe opposite endof the bnnlr and at thatfpointjis prol videdwith laterallyofl'fset bossor bosses e0.

The filler trame hasaaveb provided with a notchl, the same being' sopositioned with referei'ice to the ,bar 4:" and the lugs or offsets lilithereof, that the mainfbody of the bar i may. drop down into thenotch2,4, `while the boss l0 will engage the side surface of the har 22 andthusprevent endwise movement ofthe bar l in the direction which willpermit movement of the stake 3 which is conJ nected therewith. ltthe endof the bar l be raised'so` as to free it-rom engagement with a bar 22,the stake $3, ivill `then be free to move outivardlyso aste drop donninto the log-'freeing position or` tliatwvhich `is shown atthe righthand endet Figurel.

To insure positive dropot,` thestake when the oppositeend of the bar l is releasechfl provide thefollowing` means.

This Web 25 is rsecured to or formed as an integral part of the `filler frame,

To insure that the controlling bar 4L Willnot be released by jarringmovement incident to the movement ol the car, a logging block 5 isemployed, this being mounted upon a pivot bar which extends to theoutside of 7n the bunlrand has secured theretoa handle 5l. These partsare mountedupon the pivot bar 50 so that gravity holds them dependingtherefrom or` in the locking position.
